Corrosion is one of the most dangerous threats to the performance and longevity of an outboard motor. The two basic types of corrosion are galvanic corrosion, which results from an electrochemical reaction between different metals, and stray current corrosion, which happens when electrified metal is immersed in a grounded body of water, such as a lake, river or ocean.
Regardless of where you boat, corrosion attacks both the inside and the outside of your outboard—every day, all the time. Some forms you can see, some you can’t, and it can take only a short time for the damage to begin. Even those boating in freshwater have corrosion-mitigation duties to attend to. Why, even rainwater can have corrosive effects that can be damaging to your outboard. So it’s vital to be diligent in your anti-corrosion defense. Fortunately, both types of corrosion can be avoided or slowed.
A great deal of motor corrosion can be prevented in saltwater boats by simply flushing the motor thoroughly with freshwater each time the boat leaves the ocean. This serves the purpose of removing harmful salt deposits that can promote or hasten erosion. Additionally, corrosion occurring around exhaust outlets can be remedied by thoroughly cleaning the area with marine or auto wax.
If a boat owner notices stainless steel parts of the motor are corroding, cleaning the parts, removing foreign matter and replacing individual components if needed can solve the problem. Although corrosion is a reality of boat ownership, the good news is that it is largely preventable.
Keep a careful eye on your engine and replace or clean corroded parts as soon as you notice them. Utilize sacrificial anodes for extra protection and flush saltwater engines thoroughly after use. These simple tips, tricks and precautions will ensure that your outboard motor stays strong and corrosion-free for years.
